What effects does an increase in frequency have on sound produced?

Wave length is smaller in high frequencies.. hence a higher pitched sound...
Example, when you blow on the tip of a beer bottle, when its empty, the vibration travels all the way down the bottle and back up, hence a 'deeper' sound. the more you fill the bottle, the less room the vibrations have to move up and down the bottle, making the wave length much smaller, making the frequency higher, and the resulting sound higher pitched.

An increase in a sound's pitch corresponds to an increase in what other property?
frequency
If a sound gets louder does the wavelength of the sound it produces increase?
No. The length of a sound wave is it's frequency. Volume will increase the wave's AMPLITUDE.
The speed of sound decreases when as the air temperature cools What would this due to the frequency of sound produced by a band instrument?
As air warms up the sound wave will travel faster. The speed of sound in air depends upon the temperature. The warmer the temp., the faster the sound moves. As far as the pitch goes, I think it must depend on the instrument. My guitar goes flat as it gets warm because the strings expand slightly and become longer. In a wind instrument, as the wave travels faster in the instrument, the frequency will increase making the instrument go sharp. The speed of sound is equal to frequency times wavelength, v = f L. The wavelength is determined by the physical size of the instrument and is fixed. So, if velocity increases, and L is fixed, frequency must increase to balance the equation. The higher the frequency, the higher the pitch. So, I guess strings go flat, woodwinds, and brasses get sharp, and percussion depends on the type of instrument, how the sound is physically produced, and what material the sound must travel through.
Why car making high frequency sound when accerelating?
The answer is essentially in the question. Sound is the sensation caused by vibrations in the air. The faster the vibrations, the higher the frequency. So, when an engine is revved, the frequency of the vibrations it creates increases, and it gives higher frequency sounds, perceived as an increase in pitch.
What happens when you increase the frequency of a sound wave?
Speed = distance / time [m /s]likewise:Speed of wave = wavelength x frequency [m /s]Since sound waves travel at a fixed speed through a medium* a drop in frequency must cause a corresponding increase in wavelength*Not always true. In water of example, lower frequency waves travel faster than higher frequency waves. When this happens the waves are said to be travelling through a dispersive medium.
What effects the pitch of the sound?
frequency
An increase in a sound's pitch corresponds to an increase in what other property?
frequency
When the frequency of a sound increases do the period increase?
No. Greater frequency = less period.
When a source of sound approaches you what do you detect an increase in?
frequency
A low frequency sound is produced by a sound wave that?
An object vibrating relatively slowly produces sound waves that have low frequency and long wavelength.
How do you achieve a higher pitched sound?
Increase the frequency of vibration.
17 A sound that's produced by a single wave at a constant frequency and with no overtones is called?
A sound that's produced by a single wave at a constant frequency and with no overtones is a pure tone or a sinusoidial wave.
A sound that's produced by a single wave at a constant frequency and with no overstones is called?
A sound that's produced by a single wave at a constant frequency and with no overtones is called pure sound. This means that regardless of other characteristic properties such as amplitude or phase, the wave consists of a single frequency.
How does frequency of waves affect the pitch of the sound produced by vibrating objects?
The higher the frequency, the higher the pitch.
How the wavelength of a sound wave changes if frequency of the wave increase?
frequency of wave is inversely proportional to wavelength
If a sound gets louder does the wavelength of the sound it produces increase?
No. The length of a sound wave is it's frequency. Volume will increase the wave's AMPLITUDE.
Why is sound produced by blowing of a whistle shriller than that produced by beating of a drum?
The sound waves produced by a whistle are at a higher frequency than that of a beaten drum, causing the sound registered by human ears to be at a "higher pitch". Dog whistles can only be heard by dogs because the sound waves produced are at such a high frequency, human ears cannot detect them.
